Isky Racing Cams Valve Locks

Valve Locks too Tough to be Stamped!

Isky Racing Cams Valve Locks are constructed from heavy-duty 4140 Chrome Moly Steel that provides solid and reliable performance. The 4140 steel is heat treated so well, these valve locks can't be stamped, they have to be turned on a lathe. This process makes Isky valve locks grip the retainers with greater force and have a stronger tensile strength than any competitor.

The Super series valve locks are constructed from the same heavy-duty 4140 Chrome Moly of the standard valve locks, but are specially engineered for oval track, road and drag racing applications using roller cams and lifters.
